Humorous Book by Comedian Needs E-book Cover

This is what a business in New Zealand was looking for in their book cover design

My book 'An Asian at my Table' is on Kindle but I want a better cover designed. Cover needs my photo on it. My name is the most important text (because I have an existing audience.)

Text elements:
Author: Raybon Kan
Title: An Asian at my Table
Subtitle: Tenth Anniversary Edition
Review Quote: 'All of his columns are amusing. The best are masterpieces.' Dominion Post

Above my name it should say: Collected Humour From NZ's Award-Winning Comedian

Here's the present version (which is why I want an improved version!)

Book covers I admire:

Kindle covers need to work as thumbnails, as well as on small device screens.
